Somewhere in the 80s, probably an article in BYTE, showed how spaghetti code was structured in that program flow crossed other flow lines, while structured code had closed modules with flow that didn't cross other flow lines, but were more 'onion-shell' like in their modularity. After that, my increasing use of a structured language like C rather than continuing in my spaghetti-code BASIC programming helped a lot too.
